DMA: Split the APBH DMA init into block and channel init

2012-04-16T12:53:59+00:00

This fixes the issue where mxs_dma_init() was called either twice or never,
without introducing any new init hooks.

The idea is to allow each and every device using the APBH DMA block to
configure and request only the channels it uses, instead of making it call init
for all the channels as is now.

The common DMA block init part, which only configures the block, is then called
from CPUs arch_cpu_init() call.

tegra: i2c: Add I2C driver

2012-03-29T06:12:50+00:00

Add basic i2c driver for Tegra2 with 8- and 16-bit address support.
The driver requires CONFIG_OF_CONTROL to obtain its configuration
from the device tree.

tegra: Enhance clock support to handle 16-bit clock divisors

2012-03-29T06:12:50+00:00

I2C ports have a 16-bit clock divisor. Add code to handle this special
case so that I2C speeds below 150KHz are supported.

tegra: usb: Add support for Tegra USB peripheral

2012-03-29T06:12:48+00:00

This adds basic support for the Tegra2 USB controller. Board files should
call board_usb_init() to set things up.

Configuration is performed through the FDT, with aliases used to set the
order of the ports, like this fragment:

        aliases {
		/* This defines the order of our USB ports */
                usb0 = "/usb@0xc5008000";
                usb1 = "/usb@0xc5000000";
        };

tegra: fdt: Add function to return peripheral/clock ID

2012-03-29T06:12:48+00:00

A common requirement is to find the clock ID for a peripheral. This is the
second cell of the 'clocks' property (the first being the phandle itself).

arm: Add Prep subcommand support to bootm

2012-03-27T20:05:29+00:00

Adds prep subcommand to bootm implementation of ARM. When bootm is called
with the subcommand prep the function stops right after ATAGS creation and
before announce_and_cleanup.

This is used in command "cmd_spl export"
